-1-IORSESHOE Application filed October 3, 1918.

To all whom it may concern:

Be it known that I, HARRY A. Srrnnnnn, a citizen of the United States, residing at Cleveland, in the county of Cuya-hoga and State of Ohio, have invented a certain new and useful Improvement in. I'Iorseshoes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to horseshoes, and more particularly to shoes having detachable calks. It is the general purpose and object of my invention to provide a shoe with calks which may be readily applied to and removed therefrom, thus facilitating the repairing and replacing of such calks as occasion may require. More limitedly, my invention has for its object to so construct a horseshoe and one or more removable calks therefor as to enable the latter to be securely and conveniently anchored, and to protect from injury the portions of the shoe with which the calk or calks interlock. I secure the foregoing objects in and through the construction and arrangement of parts illus trated in the drawing forming part hereof, wherein Figure 1 represents a perspective view of a horseshoe constructed in accord ance with my invention; Fig. 2, a bottom plan view of said shoe, one of the heel calks being removed; Fig. 3 a front end elevation of such shoe; Fig. 4 a sectional view corresponding to line 4% of Fig. 3; Fig. 5 a detail in plan of a modification; and Fig. 6 a sectional detail corresponding to the line (i 6 of Fig. 5.

Describing by reference characters the various parts illustrated herein, 1 denotes the body of the shoe, which may be of any approved shape and dimensions. In view of the fact that the body of the shoe will not be subjected to such usage as will require frequent renewal, the same may be made from a drop-forging. The shoe is shown as provided with the usual toe clip 2 and with three guideways, one the toe portion and one at each of the heel portions of the shoe. The guideway 3 extends transversely of the bottom of the toe portion of the shoe and is preferably countersunk, whereby a stop shoulder 4 is provided at one end thereof, constituting an abutment for the corresponding end of the toe calk. The guideway 3 is formed as a plane surface against which the base of the call: is seated,

and along which it may slide as it is applied. to and removed from the shoe. From the central portion of this guideway there projects a dovetail rib 5 extending transversely of the toe portion of the shoe, said dovetail rib cooperating with a dovetail slot 6 in the base of the toe calk, which is shown as wedge-shaped or triangular in cross-section,

be retained against movement in one direc-.

tion in its guideway by the shoulders. and against movement in the opposite direction by means of a screw 8, preferably headless andvthreaded into the call: and projecting into a recess 9 in the body of the shoe, a convenient location for such recess being at the junction of the dovetail rib 5 with the guideway 3. The parts will. be so proportioned that the screw 8 will be generally countersunk slightly below the outer surface of the calk.

Each heel portion. of the shoe is shown provided with a guideway 9 extending forwardly from the rear end thereof, said guideways being similar to the guideway 8 and having each a central dovetail rib 10 projecting therefrom. The guideways 9 are preferably countersunk, there being a shoulder 11 at the forward end of each guideway against which the forward end of a call: 12 may abut. Each calk 12 is provided with a dovetail recess 13 of somewhat greater depth than the cooperating rib 10, for the purpose described in con nection with the calk 7. The shoulders 11 prevent forward movement of the calks 12 with reference to the body of the shoe, movement in the opposite direction being prevented by means of a screw 14: in each heel calk, which screw may be constructed and mounted in the same manner as the screw 8. The calks 12 are shown as wedgeshaped or triangular in section, it being understood that, for the purposes of my invention, it is immaterial just what shape may be given to the outer external portions of the calks.

In Figs. 5 and 6 I have shown a heel calk which extends transversely of the shoe, one

end of the shoe only being shown. in this view, the guideway 9 extends transversely of the heel end of the shoe, from the outer side of such shoe inwardly as far as a shoulder 11. The dovetail rib l0 extends transversely of the central portion of said guideway. The call: 12" is constructed in the same manner as the calks 12 and is anchored by means of a screw 1% similar in construction and mode of application to the screw 14:.

By the construction illustrated and described, it will be evident that each of the calks has an extended and firm bearing upon the supporting base provided by its guideway, that it is anchored firmly in place; and that, in use, the dovetail ribs are protected against injury and detacement by the manner of mounting the calks thereon. This enables me, as occasion may require, conveniently to remove any or all of the calks for the purpose of sharpening, repair, or renewal.

The calks may also be made of drop t'orgings and the dovetail recesses thereof as Well as the dovetail ribs may be milled to secure proper sliding engagement therebetvveen. The bases of the calks and the guideways thereafter may be machined to insure proper seating o guideways.

Having thus described my invention, what I claim is l. A horseshoe having depressed plane guideways each provided with a central the (:llhs upon said dovetail rib and having, at one end thereof a stop shoulder, fornn'sd bf, said depressions, a calk having a base cooperating with each guideway and provided with a dovetail re cess of greater depth than the cooperating rib and abut-ting said shoulder, and a screw 1 depth than its cooperating rib and abutting F said stop, and means tor securing said (:llh'fi to said shoe.

In testimony whereof. I hereunto allix my signature.

HARRY A. SIPRELLIQ.
